Enum ExtMathFn 

pub enum ExtMathFn {
    Erf,
    Erfc,
    Sin,
    Cos,
    Atan,
    Tanh,
    Cbrt,
    Rsqrt,
}

A transcendental function from the OpenCL.std extended instruction set not already covered by UnaryOp.

These extend OpenCL extended-instruction-set coverage beyond the relu/gelu/exp/log set with the elementary functions needed for activation fusions, error-function-based GELU, and angle math.

Variants

Erf

erf(x) — Gauss error function (exact-GELU building block).

Erfc

erfc(x) — complementary error function.

Sin

sin(x).

Cos

cos(x).

Atan

atan(x).

Tanh

tanh(x) (also reachable via UnaryOp::Tanh).

Cbrt

cbrt(x) — cube root.

Rsqrt

rsqrt(x) — reciprocal square root.

Implementations

impl ExtMathFn

pub fn opencl_inst(self) -> u32

The OpenCL.std extended-instruction number for a single-argument call.

pub fn name(self) -> &'static str

The lowercase function name (used as the kernel entry-point suffix).

Trait Implementations

impl Clone for ExtMathFn

fn clone(&self) -> ExtMathFn

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ExtMathFn

impl Debug for ExtMathFn

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ExtMathFn

impl PartialEq for ExtMathFn

fn eq(&self, other: &ExtMathFn) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
